Bruce Guenin Assoc. Technical Editor, Electronics Cooling INTRODUCTION JEDEC single-chip package thermal metrics are widely used as a means of characterizing the thermal performance of semiconductor packages. They correlate the peak temperature of a uniformly-heated semiconductor chip (the junction temperature, TJ) with the temperature of a specified region along the heat … [Read more...]
Hybrid Liquid-Air-Cooled Heat Sink for Extreme Environments
CoolClouds, Inc. has announced the availability of a new class of heat sinks for use in high performance computers or extreme environments starting mid-Q1 2014. According to the company, SuprCool-PC is the first “in-chassis” heat sink to cool more than 300w in the latest Intel and AMD processors without hot spots at 65°C case temperature in 25°C ambient. Comparable in size to … [Read more...]
Bitcoin Mining Boosts Interest in Liquid Cooling
A journalist's recent visit to a secret Hong Kong Bitcoin mining facility reveals some of the newer cooling techniques in use to keep server temperatures from skyrocketing. Introduced in 2009, Bitcoin is an open-source peer-to-peer electronic payment method generated through the process of “mining,” in which computers are awarded bitcoins for finding the solution to specific … [Read more...]
New Gap Filler Offers Thermal Conductivity of 1.3W/m-K
The Bergquist Company has released the Gap Pad 1450 thermally-conductive gap filler.

Magnetic Nanoparticles Prevent Hotspots in Cooling Systems
An international team comprised of researchers at MIT and in Australia has discovered a way to enhance heat transfer using magnetic fields, a method they say could prevent hotspots that can lead to system failures. The new system, which relies on tiny particles of magnetite, a form of iron oxide, is the result of several years of research on nanofluids—nanoparticles dissolved … [Read more...]
